PORTABLE UNLOADING MACHINE.

Application filed April 4, 1924. Serial no. 704,187.

I '0 all whom it may, concern:

Be it known that I, lVimnaM E. S. 'Mo ConMIoK, a citizen of the United States, residing at Rush Run, in the county of Fayettc and State of lVest Virginia, have invented certain new and useful. Improve ments in Portable Unloading Machines; and I do hereby declare the following to be a :l'i ilhrlear,and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

The priu'iary object of this invention is the provision of a machine for unloading slate or other refuse from mines and which. is portable and automatic in operation, the loaded car or other carrier being automatically dumped and returned to a position so as not to obstruct the next car to be unloaded.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

VV hile the drawings illustrate an embodi- Z5 ment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention. Y

Referring to the accompanying drawings forming a part of the application:

Figure 1 is a side view of a portable unloading machine embodying the invention, the front portion of the tip or inclined runway being broken away, i

Figure 2 is a side view of the front portionof. the tip or runway and a portion of the truck,

Figure 3 is an enlarged view of the tipple and truck, parts being broken away,

Figure 1 is a view similar to Figure 3, showing the operation of the tipple by full and dotted lines,

Figure 5 is an enlarged rear view partly in section,

Figure 6 is a side view of the tipple,

Figure 7 is a horizontal sectional view on the line 77 of Figure 6,

Figure 8 is an enlarged detail sectional view on the line 8-8 of Figure 1,

Figure 9 is adetail sectional view on the line 99 of Figure 2, and

Figure 10 is a detail view of a portion of the tipple supporting frame.

Corresponding-and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

A track 1 is preferably provided for the machine to run upon and this track maybe extended as the unloading progresses and the track may be permanent or temporary,

the truck 2 and partly upon the track 1 and is preferably of sectional formation, the front section being adapted to be secured to the rails of the track 1 in any determinate way and, as shown, a shoe 9'is adapted to 'be fitted to the tack rail and made fast thereto by clamp screws 10 which engage under the head of the ail and bind against the side web. (Fig. 9.)

. A tipple 11 is pivotally mounted upon the I supporting frame forming the superstructure of the truck 2 and is journaled between the rear ends of the side members, as indicated most clearly in Figure 5. The tipple 11 is provided at opposite sides with grooved segments 12 which are concentric with the journals 13 of the tipple and which have rigid connection with the latter to pivot therewith. A cable'l i or like connection'is attached at one end to each of the segments 12- and passes over the guide pulley 7 and is provided at its lower forward end with a counterweight 15 which normally operates to hold the tipple in a predetermined posi tion. The tipple 11 is provided at its rear end with a guide pulley 16 and beneath its rear portion with a similar guide pulley 17. The tipple 11 includes side rails 18 which are adapted to register with the rails of the tip or inclined runway 8. The rear ends of the rails 18 curve upwardly and forholding the car 19 upon the tipple, it is to be understood that other preferred means may be employed to subserve the same purpose.

A cross beam 18 connects the forward ends of'rails 18 and its horizontal flange is adapted to rest on the rails of runway 8 (Figures 6 and 7. in particular). more beams 18 are fastened to the segments 12 and to the vertical flange of cross beam 18 to brace and rigidity the latter.

A cable 20 or like part is adapted to be hitched at one end to the car 19 and. its opposite end is connected to and adapted to be wound upon a hoisting; engine which, in the present instance, is shown as comprising a'drum 21 and a suitable operatingmotor 22, said hoisting engine being mounted upon the truck 2 or like part constituting the portable base of the machine.

In the operation of the machine, it is transported to the required point of operation and is anchored to prevent movement thereofand, as stated herein, itis preferably mounted upon a track to'which it is secured in the manner set forth andshown more particularly in Figure 9. The car or other carrier containing the load tobe dumped is advanced to the tip or runway and the cable 20 is attached thereto and upon starting thev hoisting engine, the loaded car 19 is drawn over the runway and upon the tipple and when reaching the IBCUIVGCl portions 18 of the track 18, a continued operation of the hoisting engine causes the tipple to turn, as indicated by the full and dotted lines in Figure 4, thereby dumping the load. As the tipple 11 turns, the segments 12 correspondingly turn and effect a lifting of the counterweight 15, and after the load has been discharged and the drum of the hoisting engine released, the tipple is returned to normal position and the empty car retnrned to the track 1 by gravitative' action on the tipple and runway.

The empty cars may beside-tracked so as not One or to interfere with the advance of the loaded cars to be unloaded in the manner'stated herein.

.iVhat is claimed is:

1. In combination with a dumping tipple for unloading cars and the like, and. having an inclined runway leading thereto, an angular cross beam secured to the end of the tipple and adapted to rest on the end of said runway, a grooved segment secured to said tipple, a coi'lnterweight, a flexible lllOli'llJOt connecting said segment and counterweight, and a beam secured to said segment and engaging the angular cross beam aforesaid.

2.111 a portable unloading machine, a mobile bot y, a runway mounted on said body, a tipplearranged at the end of said runway, supporting means for said tipple comprising a frame on each side of the runway comprising an upright, a stay, a horizontal beam connecting said upright and stay, and a brace secured to the mobile body intermediateof the upright and stay and to the joint between the upright and horizontalbeam, the tipple being pivoted at the end of said stay, a grooved segment carried by the tipple, a counterweight, and a flexible element connecting said counterweight and grooved segment and trained over a pulleyon the brace aforesaid.

3. A machine of the class described having a mobile body, an inclined runway extending partly across and supported by the body, a transverse shaft carried by the body, a tipple pivotally mounted by said shaft, said tipple being inclined and. at its forward end resting on said runway, a car adapted to travel on said runway and tipple, means on the tipple engageable by the car to limit the movement of the latter onto the tipple and to hold the car during emptying, a hoist carried by said body, and an operative connection from said hoist to said car engaging the tipple, whereby the car may be moved onto the tipple and the car and tipple thereafter unitarily tilted to empty the car, a segment carried by said shaft, a flexible element connected to said segment, a weight connected to said element, and means on the body guiding said element.

In testimony whereof I aflix my signature.

WILLIAM E. S. MCCORMICK.
